FUEL AND LUBRICANT
WARNING
Alternative fuels, such as E-15 (15 % ethanol),
E-85 (85 % ethanol) or any fuels not meeting
ECHO requirements are not approved for use
in ECHO 2-stroke gasoline engines.
Use of alternative fuels may cause
performance problems, loss of power,
overheating, fuel vapor lock, and unintended
machine operation, including, but not limited
to, improper clutch engagement.
Alternative fuels may also cause premature
deterioration of fuel lines, gaskets, carburetor
and other engine components.
IMPORTANT
• ECHO brand 2-stroke oils may be mixed at
50:1 ratio for application in all ECHO engines
sold in the past regardless of ratio specified in
those manuals.
• Use of unmixed, improperly mixed, or fuel older
than 90 days, (stale fuel), may cause hard
starting, poor performance, or severe engine
damage and void the product warranty. Read
and follow instructions in the Storage section of
this manual.
FUEL STATEMENT
Gasoline - Use 89 Octane [R+M/2] (mid grade or
higher) gasoline known to be good quality. Gasoline
may contain up to 10% Ethanol (grain alcohol) or
15% MTBE (methyl tertiary-butyl ether). Gasoline
containing methanol (wood alcohol) is NOT ap-
proved. Use of ECHO branded fuel is recommend-
ed to extend engine life in all air-cooled 2-stroke
and 2/4-stroke hybrid engines.
Two-Stroke Oil - A two-stroke engine oil, such as
ECHO branded 2-stroke oils, meeting ISO-L-EGD
(ISO/CD 13738) and J.A.S.O. FD Standards must
be used. ECHO branded 2-stroke oils meet these
standards. Engine problems due to inadequate
lubrication caused by failure to use an ISO-LEGD
(ISO/CD 13738) and J.A.S.O. M345-FD certified oil
will void the two-stroke engine warranty.
